DEROVEMIBNT IN COMBINED SAFETY-ATTACHMENT AND BRAKE FOR CARRIAG-ES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whmn it may concern:

Be it known that l, CLAUDE Dccnnox, of the city, county, and State oi'New York, have made and in vented new and useful Improvements in Sai'cty-Att:tclnnent to Carriages, and that the following is a full, clear, and c act description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, t'ormin part of this specification, and in which- Figure 1 represents a longitudinal vertical section of a carriage provided with my improved satetv-attachment;

Figure 2 is an inverted plan view of the same;

Figure 3 is a ii'ont elevation of the same, partly in section; and- Figure 4 is a detail top view of the front end otihc pole.

- Similar letters of reterence indicate correspomling parts.

This invention relates to certain improvements on the satiety-attachments for carriages, for which Letters Patent, No. 60,705, were granted to me on the 1stday of February, 1867; and

' he invention consists First, in so connecting the operating-lever with the brake and detaching-apparatus, that either the brake alone, or both the brake and the dctaclling-apparatus, can, by one move of thc lever, be operated. The object is to allow the same lever to apply the brakes, ii' the carriage or wagon is moving down-hill, or is drawn too quickly, without necessitating at the same time the detaching oi the horses; and

Second, the invention also consists in a novel device for operating the dctaching-apparatns. This device is perfectly simple and eii'ective, and consists only of a series of sliding bars connected, by means of a chain,

-with the rock-shalt, from which the al'oresaii'. operati uglever projects. This chain runs along the edge of a pillley, which has its axis in line with the king-bolt, so that the length of chain will not be aficctcd by the turning of the front axle of the wagon.

A, in the drawing, represents the body oi a carriage or wagon of ordinary or suitable construction;

B is the front axle;

C, the hind axle;

D 1) are the wheels;

E is the head-block above the front axle;

F is thciitth-wheel; and

a, the king-bolt.

All these parts -are arranged as ordinary or usual; so me, also, the pole G and cross-bar H, secured to the same.

I is a horizontal rock-shaft, having it-s bearings in any suitable part of the wagon-body.

From this shalt project upward lugs or cars, 12 b, or a lug or ear, 1;, to which the front end oi'a chain, J, is secured that reaches back to and turns the rock-shalt K,bymcans of which the brake-shoes c are operated.

The chain J passes over a pulley, ll, so that its front part is radial to the axis of the shaft 1, and thus, in whatever direction the shaft 1 may be turned by means ofa lever, L, projecting from it, the chain will always e pulled and the brakes applied.

A spring, s, applied to the nmchanism in a suitable manner, brings. the parts back to their original position as soon as the lover I) is released.

From the front-end of the shaft 1 projects a lug, e. The same is, by means of an endless chain, M, connected with the rear end of a sliding bar, N, which bar mores above the rear end of the tongue. It is held tin-ward by means of a spring, f, by means of which the chain M is also kept tense.

0n the limit end of the bar N is formed a plate or box, 1 in which oblique slots are arranged.

Pins h 1:, that project from bars 0, which slide on the cross-bar ll, tit into the slots of the plate as shown in iig. 2. I

From the bars 0 project ears 1', on which pins jj are arranged, which pins tit through lugs Z I that project from the cross-bar, as is clearly shown in fi 3, thereby holding the traces or whitiietrees between such lugs.

When the lever L is turned lbrwiu'd, as per arrow 1 in fig. 1, the brake is applied, but the chain M is slackencd, and the detaching-a mnratus is not operated; but when the lever L is moved backward,'as per arrow .2, the chain M will be stretched; thereby the bar N will be drawn back, the pins I: h and their bars 0 will, by the oblique slot, be caused to move laterally, and thcreby the traces or the \vhililetrees are disengaged.

With the bar N may also be directly connected at bar, 1, which moves on the pole (l, and which is branched at its front end, as shown in h'g.4, and carries pins, 1):, that hold the pole-straps bctwee-n cars a a, projecting from thc'pole, so that these pldestraps can also be detached by the said motion ol'ihc lever [1. Thus, by moving the lover I) one way, the brake only will be applied, and by moving it in the other direction, both the brake and tho iletacl1hug-apparatus will be operated at once.

The chain M passes along, both sides of a pulley, 0, which is l'ormcd mi the king-bolt, or on an extension of the same. Thereby the length of chain between the lug v and the bar N is always maintained equal, even it the front part of the carriage is turned at considerable angle, as indicated in lig. 2. I

All these improvements may also be applied to two-wlnrcl snlkii-s, as well as to all sorts of one-horse double-shalt carriages or wagons.

llaving thus described my invention,

l elaim as new, and desire to'secure by Letters l.'atcnt l. The rock-shalt I, when combined with the brakes and detaching-apparatns of a wagon or carriage in such a manner that when the said shaft is turned iuoue direction the brake only is applied, while both the detachingappnratns and the brak will be operated when the shaft is turned in the other direction, as set forth.

2. So connecting the brake-rod or chain J with the crank on the rock-shaft I, that the brakes will be applied in whatever direction the said shaft may be turned, as set forth.

3. Connecting the rock-shaft I by means of a chain, M, with the sliding bar N, on which the slotted plate g is arranged or formed, which plate, when moved longitudinally, imparts lateral motion to the bars 0, substantially as and for the purpose herein shown and descn'hed.

4.- The pulley or wheel 0, having its axis in line with that of the king-bolt, in combination with the chain M, sliding bar N, and rock-shaft I, all arranged and operating substantially as herein shown and described, for the purpose specified.
